Employee GPS Tracking Laws in Wisconsin: When Is It Legal?

Federal law does not specifically prohibit GPS tracking of employees. The Electronic Communications Privacy Act (ECPA), 18 U.S.C. § 2511, prohibits interception of wire, oral, and electronic communications, but GPS location data is generally not considered an intercepted communication under federal law. The ECPA includes a business use exception that allows employers to monitor communications made on company systems for legitimate business purposes. However, employers cannot track personal devices without consent. The National Labor Relations Act, 29 U.S.C. § 151 et seq., may restrict tracking that interferes with union organizing or protected concerted activity. The Americans with Disabilities Act, 42 U.S.C. § 12101 et seq., requires employers to maintain medical privacy and could limit tracking that reveals health information. No federal agency provides specific guidance on employer GPS tracking, though the Department of Labor and EEOC address tracking in the context of wage and hour compliance and discrimination.

Federal courts have generally held that employees have limited privacy expectations in tracking of company vehicles and equipment during business hours. However, personal device tracking and off-duty monitoring face stricter scrutiny. Enforcement is primarily through private litigation under tort law and potential NLRA violations.

Wisconsin Statutes § 134.43 requires employers to provide employees with notice before implementing electronic monitoring, including GPS tracking. The statute does not ban tracking but mandates transparency. Wisconsin Statutes § 995.50 regulates wiretapping and interception of oral and electronic communications; GPS data alone is not typically considered an intercepted communication, but location data combined with communication content may implicate this statute.

Wisconsin recognizes a tort cause of action for invasion of privacy under common law (Wis. Stat. § 895.50). This means employees can sue employers for tracking that violates a reasonable expectation of privacy. Wisconsin courts balance four factors: (1) the extent to which the employee knew of the employer's monitoring, (2) whether the employee consented, (3) whether the monitoring was limited to business purposes, and (4) the nature and sensitivity of the information collected.

Wisconsin law is weaker than some states (like California) which explicitly restrict employee monitoring. However, it is stronger than states with no monitoring notice requirements. Wisconsin applies a reasonable expectation of privacy standard, which protects employees from covert tracking of personal devices and off-duty conduct. Employers are covered if they operate in Wisconsin regardless of size; no employee threshold applies.

Unique Wisconsin protections include the explicit notice requirement in § 134.43, which creates a statutory duty to inform employees before monitoring begins. This is more protective than federal law, which has no general notice requirement. Wisconsin also recognizes invasion of privacy as grounds for civil damages, which is available to all private sector employees. Public sector employees in Wisconsin may have additional rights under the Wisconsin Constitution Article I, § 1, which recognizes privacy rights.

Wisconsin law contains several important exceptions and limitations. First, tracking of company-owned vehicles and equipment used for business purposes is generally permissible without consent, provided notice is given under § 134.43. Second, employers may track location during work hours on company devices more readily than off-duty tracking. Third, if an employee consents to monitoring, the employer is protected from tort liability for invasion of privacy.

Wisconsin recognizes a legitimate business purpose exception; employers can track assets to prevent theft, monitor productivity, ensure safety, and verify billable hours. However, this exception is narrower for personal devices or off-duty conduct. Employers are not required to use the least restrictive monitoring method, but excessive or intrusive tracking may still violate the reasonable expectation of privacy standard.

Another critical exception: if the employee is in a union and the collective bargaining agreement restricts monitoring, the CBA may override employer policies. Wisconsin is not a right-to-work state, and union protections are strong. Additionally, employers cannot track employees in locations where privacy is expected, such as bathrooms, locker rooms, or private areas. Tracking that reveals protected information—such as medical appointments or union activities—is more heavily scrutinized.

Employees have limited recourse if they did not receive notice but consented verbally or impliedly by accepting employment; courts look at whether consent was informed. Finally, whistleblowers and employees engaging in protected concerted activity have additional protections, and tracking that interferes with these activities may violate the National Labor Relations Act.

Step 1: Document the tracking. Keep detailed records of when you discovered the GPS tracking, what device or vehicle was tracked, what information was revealed, and how you learned about it. Save emails, screenshots, notices, or messages from your employer about monitoring. Record dates and times of tracking if possible. Document any unusual behavior by the employer—such as knowing your location at unexpected times or referencing your movements without explanation. Create a timeline of events.

Step 2: Determine if notice was provided. Review your employee handbook, onboarding materials, and any written policies. Check emails from your employer for monitoring notices. If tracking was not disclosed before implementation, this is a violation of Wisconsin Statutes § 134.43. If notice was provided verbally, note the date and details. Determine whether you consented, explicitly or implicitly. If you did not consent and were not notified, your claim is stronger.

Step 3: File a complaint with the appropriate agency. For potential violations of Wisconsin's electronic monitoring notice requirement (Wis. Stat. § 134.43), file a complaint with the Wisconsin Department of Labor, Privacy and Records Section at 608-266-3136 or visit dol.wi.gov. Provide documentation of the monitoring and lack of notice. The deadline to file is not statutorily defined, but prompt action is advisable. If the tracking may implicate the National Labor Relations Act (such as tracking union organizing), file with the National Labor Relations Board (NLRB) at nlrb.gov or call 1-844-762-NLRB. For federal wiretapping violations (if communications were intercepted), consult an employment attorney before filing, as federal claims carry different procedures.

Step 4: Expect the investigation process. The Wisconsin Department of Labor will review your complaint and contact the employer for a response. The employer must explain the business justification for tracking and whether notice was provided. If notice was not provided or consent was not obtained, the department may issue a citation or order corrective action. The investigation typically takes 4–8 weeks. The NLRB investigation process is more formal and may include interviews, document review, and a hearing if the complaint is meritorious.

Step 5: Consult an employment attorney if the violation is serious, if the employer retaliates, or if you suffer damages. Contact the Wisconsin Employment Relations Commission or hire a private attorney specializing in privacy law or employment discrimination. An attorney can evaluate whether you have a tort claim for invasion of privacy under common law, which may entitle you to damages for emotional distress, lost wages, or punitive damages. Many employment attorneys in Wisconsin offer free initial consultations.
